You just got home after a long day of classes, exhausted from the recent workload your professors dumped on you. After spending the evening in the library studying, your brain felt fried from schoolwork, seeking any form of entertainment that didn't require a lot of mental use. You set your bag down on the couch, noticing your roommate, Akechi, wasn't anywhere nearby. You walked to the kitchen to grab some snacks and a drink, walking back to your own room when you heard noise from behind the slightly ajar door of Akechi's room.
Nudging the door open quietly, you peeked inside to see Akechi; his back faced you, scribbling down something in a notebook, papers and files strewn haphazardly across his desk. He was usually so organized, even if he wasn't acting with his typical "Detective Prince" facade in front of you anymore, so seeing this was a little unusual. Squinting harder at some of the documents, you could make out something about a fraud case.. Akechi still worked as a detective, but even you were aware they worked him as hard as anyone else, for a college student.
Either he didn't notice you or didn't acknowledge your presence, continuing to scrawl rapidly on the full looking page.
